I have one,a B13 Sport Advance.There is a learning curve to one,but once you get the knack of it,it's all smiles.They will bull their way through stuff that will stop many ATVs,and use very little fuel.I only got mine because someone bailed-out on their order.Still took 2 months to get it last fall/winter,and there was a substantial price increase since.Mine was 4100.00 out the door with sled/hitch,now I see the same model lists for 4999.99 without sled.
The one fault I see with mine,is the way the engine is set-up.Briggs 2100XR has no fuel primer and has a governor.It's really set-up for stationary use,like pressure washer or generator.And the gearcase should have a neutral position.A little cold-blooded,just have to run longer on full choke.But not much worse than a carbed 4-stroke ATV.
Storage is great,mine is on 2 Harbor Freight furniture dollies,and can roll it into garage corner with ease.I looked into transporting on a scooter carrier,but most reviews said they were flimsy junk.A well built one weighs too much,I just use a 4x6 trailer with sides.Or ramp it into the back of a truck,2 guys can pick it up,does not weigh much.
